CASEMENT-WINDOW-OPERATING MECHANISM.

Specification of Letters Patent.

Application filed March 18, 1912.

Patented Mar. 1'7, 1914. Serial No. 684,579.

To all whom it may concern:

Be it known that I, Jnssn N. VVA'rsoN, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Casement Window Operating Mechanism, of which the following -is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, refcrence being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a to plan view partly in horizontal section 0 my improved casement window operating mechanism. Fig. 2 is a similar view enlar ed. Fig. 3 is a side ele vational view partly in section.

This invention relates to a new and useful improvement in casement window operating mechanism, the object being to construct a. device of the character described, the parts of which are reversible, so that the mechanism may be used for right and left-hand windows.

In the drawings: 1 indicates the easement window and 2 the frame thereof.

3 is a base plate provided with suitable openings through which wood screws 4 may be passed to secure the frame in position. This frame has upturned marginal edges 5 constituting a bearing for a removable operating rod 6.

7 indicates a screw formed with an opening to receive the rod 6, said screw being held in position on the rod by means of a in 8. 9 indicates a segment whose teeth cooperate with the worm screw, said segment be ing removably mounted on the base plate 2 y provided witha head at its up er end and passes through an opening in t e base plate to receive a washer ll'held in position bly means of a screw 12. A sleeve 13 s aces t e segment from the base plate and olds said segment elevated in proper alinement 14 indicates a slottedarm secured to the segment by means of the stud 10 heretofore described and a stud 15 passing through the heel of said arm and the segment, as shown per end and cooperates with a washer 16 on its lower end which. is held in position by means of a screw 17 A sleeve 18 spaces the heel of the arm from the segment, while a sleeve 19 surrounding the stud 10 performs a similar function.

20 indicates a bracket secured to the inner face of the easement window and having a roller 21 operating in the slot of the arm 14. The outer end of rod 6 is provided with a crank handle 22 by which the worm may be turned and the easement window opened or closed in a manner which will be apparent from the drawings.

The parts entering into the construction of my improved operating mechanism are designed to be re-assembled in order that the mechanism may be used for either right or left-hand windows. shown in Figs. 2 and 3 is intended for use in connection with the ri ht hand window, but if it is desired to use he same or similar parts for a left-hand window as shown at the left, Fig. 1, 'the screw 12 is removed after which the screw 17 is removed and the arm reversed in its position relative to the easement. The cotter pin 8 may be removed, so as to permit the worm 7 and the rod 6 to be reversed, after which the arts are re assembled as shown at the let in Fig. 1. The object of elevating the arm 14 above the segment is to permit the device, when positioned between the stool and the sill, to cooperate with the bracket 20 which is positioned above the lower edge of the casement window.

What I claim is:

1. In a device of the class described, a base plate provided with ears and a pivot pin, an operating shaft journaled in said ears and reversible with reference to said base plate, a worm carried by said shaft and reversible with reference thereto, a segment adapted to cooperate with said worm mounted on said pin and reversible with reference thereto, and a lever arm attached to said segment and reversible with reference thereto.

2. An operating mechanism for casement windows comprising a base plate, an operating shaft reversibly mounted therein, a worm gear reversibly mounted on said shaft, a pivot pin mounted on said base plate, a

The construction sleeve carried by said pivot pin, a toothed signature in the presence of two Witnesses, segment reversibly supported on said sleeve this 26th day of February, 1912.

and meshin With said worm gear anci a lever reversb1y pivoted on said pivot pin JESSE WATSON and having one end connected to said seg Witnesses:
